Hello there!
I do not know what the statements are but i will explain some characteristics of the beach to you!
Beaches are made of sand, they are along the coast, the coast is when a state (such as California) is along the beach, or the ocean, beaches also sometimes have trees, but usually when the ocean rises the ocean takes the tree into its depths. That's why sometimes you see tree trunks on the beach, but be careful sometimes if you sit on them they will cave in because of all the salt it absorved from the oceans water, sometimes you will see seagulls, seagulls like to eat the fish from the ocean, and/or the crabs that wash up on shore.
I hope this helped you! 
Good luck!
 
        
             
        
        
        
Scientists use triangulation to find the epicenter of an earthquake. When seismic data is collected from at least three different locations, it can be used to determine the epicenter by where it intersects. Every earthquake is recorded on numerous seismographs located in different directions. Each seismograph records the times when the first (P waves) and second (S waves) seismic waves arrive. From that information, scientists can determine how fast the waves are traveling. Knowing this helps them calculate the distance from the epicenter to each seismograph.
To determine the direction each wave traveled, scientists draw circles around the seismograph locations. The radius of each circle equals the known distance to the epicenter. Where these three circles intersect is the epicenter.
